Offshore trim pump issue
Bit of a strange one here, have replaced the trim pump on the phantom 18 to the later type with the plastic resorvoir. The engine trims fine on the land with no leaks or issues at all, however anything over 5mph the engine won't trim up but will trim down fine? If your going slowly it will trim up fine. When the engines on the land you can stand on the engine and it trims up fine so doesn't appear to be a load thing. Has anyone else had a similar issue?
